Not that I want to become the LAT clipping service, but:
You know that iconic photo of Elvis and Nixon shaking hands?
Yeah, that one.
Anyway, the LAT has an interesting article on how this photo came about.
Copies of that photo — the president in his charcoal suit, the king of rock ‘n’ roll in his purple velvet cape — are requested more than just about any of the archives’ treasures, including the Constitution.
You can request copies of the Constitution from the National Archives? Can I request copies and have them sent to other people?
There’s also a section devoted to this photo on the NARA website.
